A new enzyme immunoassay for alpha-fetoprotein in a separate setup coupling an aluminium/Prussian blue-based self-powered electrochromic display with a digital multimeter readout

A new enzyme immunosensing platform was designed for the simple, rapid and sensitive detection of disease-related biomarkers (alpha-fetoprotein, AFP, was used as a model in this case), coupling an aluminium (Al)/Prussian blue-based self-powered electrochromic display with a digital multimeter readout.
